Ajax Chemicals. Birthplace of the Joker. The Joker fell into a vat of chemicals long ago and a villian was born. There were several chemicals mixed in the vat that The Joker fell in that twisted his face so that he had a permanent smile on his face. It was several years later when Joker befriended Harleyquin (or just "Harley" for short). Tonight, Joker and Harley had gone to Ajax Chemical to investigate a brand new chemical made by Ajax; Chemical V. Chemical V was still in the planning stages, and they had tested the chemical on several human volunteers. The effects of Chemical V on the human body were highly classified, but that didn't stop the Joker from getting a tape of one such experiment on a young woman with red hair. After taking Chemical V, the young woman ate the person who had given her the chemical in one gulp! The fate of the sciencist that was eaten by the young woman is unknown...though, he was persumely digested. After that experiment, the U.S. Government ordered Ajax Chemicals to stop producing Chemical V. The Joker had other plans.
Ajax Chemicals were on the outskirts of Gotham City and was empty on the night where Joker and Harley went there.
"Just think" said Joker. 'we could be rid of Batman and that pesky Batgirl for good if we get our hands on that Chemical V"
"Sounds like a plan, Mr. J" said Harley.
The two villains came to a huge vat that was marked "Chemical V". It had a label on it:


CHEMICAL V
Experimental Batch
Created 8:34 AM, today


"They're still making this stuff?" asked Harley. "I thought the..."
"Shh!" said Joker. "I thought I heard something"
Harley listened for anything, but heard nothing.
All of a sudden, Harley found herself falling into the vat of Chemical V.
"Oops" said Joker. Joker had pushed Harley into the vat.
